– A box with a flap at the top and a small square to squirt paint into
– two to three gears of different sizes per spin art machine
– Lego motor
– Lego beams
– Axles

Preparation and Set Up:

– Prepare a box with a flap opening and a small square opening at the top of flap.
– Prepare one box per group of students
– split students into groups of 4-5 per group
– Assemble a kit with a few axles, lego beams, and a few gears of different sizes

Necessary Background

Understand how to use motors.
Understand basics to gears

Procedure

Have students construct a small machine using a few Legos and gears. Once the students build the machine, attach a motor to the axle of the gear system.

Modifications:

When building gear system, advise students to make a simple gear system. More than two gears will make a gear train that will be hard to move with the motor.
